Car roof



Patented Mar. 1, `1932 UNITED STATESI PATENT OFFICE CHARLES DAVID BONSALL, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOB TO P. H.

MURPHY COMPANY, OF NEW KENSINGTON,

PENNSYLVANIA.

PENNSYLVANIA, A CORPORATION OF CAR ROOF Application ledA July 11,

This invention relates to car roofs of the all-steel riveted-up type wherein self-supporting roof sheets extend from side to side of the car and are rigidly connected along their adjacent margins by upstanding. seams that function as outside carlines and have members secured therein for suspending lifting beams beneath said roof sheets.

The principal object of the present invention is an arrangement of the running board for car roofs of the above type which for a given head room will decrease the overall height or for a given overall height will increase the head room. Other objects are simplicity and cheapness of construction, fewness of parts and compactness of design.

The invention consists in the car roof and in the construction, combinations and arrangements of parts hereinafter described and claimed. i

In the accompanying drawings, which form part of this specification and wherein like symbols refer to like parts wherever they occur, A

Fig. 1 is a plan view of a portion of a car roof embodying my invention,

Fig. 2 is an enlarged transverse section through one-half of the car roof on the line 2-2 in Fig. 1,

Fig. 3 is a vertical cross-section through one of the roof seams at the ridge on the line 3 3 in Fig. 2,

Fig. 4 is a vertical cross-section through the eaves portion of the car, the section being 5 similar to that shown in Fig. 2 but on a slightly larger scale; and

Fig. 5 is a Vertical cross-section similar to Fig. 3 showing a modified form of construction.

Referring to the accompanying drawings, my invention is shown in connection with an all-steel, riveted-up,` single-course car roof comprising self-supporting roof` sheets A, which span the car from side plate B to side plate B and slope downwardly on opposite sides of the ridge. The side plates B are preferably of Z-shape cross-section and are disposed with their webs horizontal and with their inner flanges extending upwardly. The o roof sheets A are provided with depending 1930. Serial No. 467,260.

eaves flanges 1 that overhang the upstanding inner flanges of the side plates B and are rigidly secured flatwise thereto by horizontal rivets 2. The roof sheets A are provided along their adjacent side margins with up-s'tanding seam flanges 3 and have their body portions offset upwardly adjacent to said flanges to form raised panels 4 at the side margins of the sheets.

The roof sheets A are arranged on the car side by side; and metal seam caps C of substantially inverted U-shaped cross-section are placed astraddle the adjacent side marginal seam flanges 3 of said sheets and are rigidly secured to said flanges by horizontal rivets 5, thus constituting outside carlines for the roof. The seam caps or carlines C extend from eaves to eaves of the car and are provided at the lower' edges 0f their side Walls with outstanding base flanges 6 that rest on the raised side marginal panels 4 of the lroof sheets and are turned down at the eaves over the depending eaves flanges of the sheets. As shown in the drawings, the seam caps C are of greater depth at the ridge than at the eaves and their base flanges 6 are wider at the eaves than at the ridge. Suitable hanger plates 9 may be embodied in the seams at the ridge for suspending a load-lifting device (not shown) from the roof.

A running board E extends longitudinally j of the car at the ridge. Said running board comprises sections 14 located between adjacent seams with their upper surfaces disposed substantially at the level of the highestpoints of the seam caps or carlines C and with their ends in abutting relation to the sides thereof. The ends of the running board sections 14 are secured to the seaml caps C by means of angle brackets 15 disposed on opposite sides thereof with one flange down and secured flatwise to the sides of said seam caps bythe rivets 5 which secure them to the roof sheet flanges 3. The other flanges of the angle brackets 15 project outwardly on opposite sides of the seam caps and thus serve as supports for the ends of the running board sections which are removrunning board sections 14 are covered by means of galvanized iron flashing strips 17 whose side margins are nailed or otherwise secured iatwise to the top surfaces of said sections. The purpose of the fiashings 17 -is to prevent water and cinders from lodging between the ends of the running board sections and the sides of the seam covers and causing rust.

in the modified construction shown in Fig. 5, the portion of seam cap located between the spaced ends of the running board sections is protected by means of a sheet metal ashing 16a which is provided along its middle with a hollow upstanding rib 16?; that straddles the seam cap and is provided with lateral base flanges 16e that rest on the running board supporting brackets beneath the running board sections.

By the arrangement described, the sections of the running board are located between the upstanding roof seams instead of extending across the tops thereof and thus function after the manner of struts for maintaining a proper spacing of the seams at the ridge and for preventing said seams from tilting crosswise. lit is noted that with this arrangement of the running board sections the outside height of the car may be reduced without decreasing ythe head room thereof or the head room of the car may be increased without increasing the outside height thereof.

The invention is not restricted to the precise arrangements of parts shown and described.

What l claim is:

1. A car roof comprising roof sheets connected along their adjacent margins by seams that extend transversely of the car, and a running board extending longitudinally of said roof, said running board comprising sec tions located between adjacent seams and extending below the tops thereof.

2. A metal car roof having upstanding ribs that extend transversely of the car, and a running board extending longitudinally of said roof, said running board comprising sections located between adjacent upstanding ribs and extending below the tops thereof.

3. A car roof provided with outside carl lines that extend transversely of the car, and

a running board extending longitudinally of said roof, said running board comprising sections located between the adjacent `carlines and extending below the tops thereof.

4. A car roof provided with outside carlin-es that extend transversely of the car, a running board extending longitudinally of said roof, said running board comprising sections located between the adjacent carlines and extending'below the tops thereof, and flashing members secured to the ends of adjacent running board sections and having holreame? low ribs covering the portions of the seams located therebetween.

5. A car roof comprising roof sheets connected along their adjacent margins by upstanding seams that extend transversely of the car, a running board extending longitudinally of said roof, said running board comprising sections locatedbetween the adjacent seams and extending below the `tops thereof, and flashing members secured to the ends of adjacent running board sections and covering the portions of the seams located therebetween.

6. A car roof comprising self-supporting roof sheets extending from eaves to eaves of the car and connected along their adjacent margins by upstanding seams that slope downwardly on opposite sides of the ridge, and a running board extending longitudinally of the car, said running board comprising sections located between adjacent seams with their upper surfaces disposed substantially at the level of the highest points of said seams.

7. A car roof comprising self-supporting roof sheets extending from eaves to eaves of the car and connected along their adjacent margins by upstanding seams, a running board extending longitudinally of the car,

said running board comprising sections that are spaced apart on o posite sides of said seams and extending be ow the tops thereof, and sheet metal dashing members having hollow ribs adapted to straddle each seam cover and outstanding flanges that are overlapped by and are secured to the ends of adjacent running board sections. v

8. A car roof comprising roof sheets connected along their adjacent margins by seams extending transversely of the car, a runnin board extending longitudinally of said roo said running board comprising sections l0- cated between the adjacent seams, and means for securing the ends of adjacent sections to the opposite sides of saidseams, said means comprising angle brackets secured to the opposite sides of the seams and extending outwardly therefrom below the level of the highest points of said seams to form supports for the adjacent ends of the running board sections.

Si ned at New Kensington, Pennsylvania, this th day of July,`1930.
